Why a Gas Log Fireplace Won't Turn On

Shutoff Switch

• A gas fireplace may not start because a gas shutoff switch is in the off position. Gas shutoff switches for home appliances are usually in a utility room or basement. Gas cannot reach the fireplace if the shutoff switch is in the off position. It’s possible a worker may have turned off the switch while performing maintenance on another appliance. If necessary, ask a gas appliance repair person or your propane delivery agent to show you where the gas shutoff is for the fireplace. Confirm that the switch is turned on and try starting the fireplace again.

Wall Switch

• Gas fireplaces may also feature a wall switch in the same room as the fireplace. The fireplace will not turn on if the wall switch is in the off position. The wall switch must be on to allow gas flowing through the shutoff switch to reach the fireplace.

Pilot Light

• A pilot light that will not stay lit can also cause the gas fireplace not to light. The pilot light is a small flicker that is usually always on. The flame is an ignition source for larger flames as you turn on the fireplace and increase the flow of propane or natural gas. Without the pilot light, your fireplace may not start.

  You can restart the pilot light yourself. The Knoxville News Sentinel, however, reports that the process varies with different brands of gas log fireplaces. Consult your owner's manual for specific instructions. Do not proceed if you smell gas during the process.

  Usually, you must find a control knob below the fireplace with settings for "On," "Off" and "Pilot." Turn the knob to the "Off" position for five minutes. Then turn it to the pilot position. Press a separate ignition button in the same area to start the pilot light. If that does not work, use a long lighter or long match to start the pilot light. Finish by turning the knob back to the "On" position.

Considerations

• There may be other problems once the fireplace is turning on properly. A new fireplace may produce an odd smell and smoke. But this usually stops after the first six hours of operation, according to one manufacturer. Check batteries in the remote if the fireplace will not turn on by remote control. Do not attempt to repair a gas fireplace yourself. It’s fine for you to check on/off switches, but leave pilot light repair to a professional.
